Hacking Setting multiple patches in Riivolution

[ctkxtreme]

So I'm trying to mod again Disney Sing It, a karaoke game. I was able to successfully use Riivolution to patch the game and bring over more songs. However, there is a limitation where having more than 49 songs will cause the game to crash. As such, I want to set up another patch so I can allow different mods and change songs with the same game, as well as changing the save file. I've tried to look up information about this but my results haven't gone much anywhere. So how would I go about doing this? The Smash mods kinda gave me some idea, but I feel it'd be better to ask directly here.
